Structural cardiac defects occur in at least 1 twin in about 75% of conjoined twins with thoracic level fusion. Outcomes after surgical separation of thoracic level conjoined twins have been favorable when the hearts have been separate. However, even in this situation, the outlook is poor for an individual twin with an important cardiac defect. Arterial anastomosis between twin circulations is an important additional consideration, with poor outcomes for perfusion recipient twins. Surgical separation is contraindicated when ventricular level cardiac fusion exists. Cardiac assessment is a key component of prenatal counseling.

Conjoined twinning is a special case of monozygotic, monoamniotic twinning. Human conjoined twinning, and vertebrate conjoined twinning in general, is a very rare phenomenon. It has been suggested that the risk of conjoined twinning increases with some medication and upon assisted reproduction.

Conjoined twins, although rare, present unique challenges in surgical management, particularly regarding skin closure after separation. This case report details the successful separation of pygopagus conjoined twins using a rectangular skin flap technique. The twins, joined at the lumbar and sacral regions, underwent meticulous preoperative planning and collaborative effort from multiple medical teams.

Article Synopsis
- Conjoined twins, or Siamese twins, are a rare type of monochorionic twinning requiring specialized imaging for diagnosis and monitoring.
- Ultrasound is typically the first choice for screening, while MRI provides detailed anatomical information when needed.
- A case of first trimester thoraco-omphalopagus conjoined twins with cystic hygroma was thoroughly evaluated using both sonography and MRI, highlighting the importance of advanced imaging in accurate diagnosis.
